ABSTRACT:
Lighting object for providing a light show to an observer. The lighting object includes at least two LEDs, each of which emits light of a different wavelength, and a microcontroller for independently controlling the intensity levels of the at least two LEDs to vary colors perceived by the observer during the light show. The light show includes at least one segment for which a memory stores, for each of the at least two LEDs, a target intensity level and timing information. The microcontroller calculates a plurality of intermediate intensity levels for the at least two LEDs for the duration of the segment based on a starting intensity level, the target intensity level, and the timing information for each of the at least two LEDs. The microcontroller also controls the at least two LEDs to operate at each of the calculated intermediate intensity levels during the segment.
